Drive
This term refers to the acceleration generated during a turn. Applying water pressure against a board's fins or rails will produce a rebound effect. A good comparison is a competitive swimmer approaching a pool's wall. He wants to change direction so he pushes off the wall with his feet and accelerates in the process. The same principle is in effect when a surfer engages his fins to change direction.
